Also, in this particular case, the offending call is in your own code, so how about print()ing the arguments to runif() before running it?

I.e, insert

print(f$d[[n.of.u.vars+n.of.o.vars+j]][[2]][1:2])

at the beginning of the for loop below

(You likely don't really want to grow X on every call to runif(), but that is a different matter)
